DABBING API ARA'TUS FOR WOOL-C(JMBING MACHINES.

SPECIFICATION forming part of Letters Patent No. 650,601, dated May 29,1900. Application filed October 2, 1899. Serial No. 732,281. (No model.)

To aZZ whom it may concern:

Be it known that I, JoNAs DENBY, a subject of the Queen of GreatBritain, and a resident of Oxenhope, near Keighley, in the county ofYork, England,-have invented certain new and useful Improvements inDabbing Apparatus for VVool-Combing Machines, of which the following isa specification.

My invention relates to improved dabbing apparatus for wool-combingmachines of the class known as Nobles combs; and it 0011- sists inproducing, constructing, and arrangin g said apparatus so that thedabbingbrushes heretofore employed may be entirely dispensed with by thesubstitution of better, more durable, and efiicient devices.

In the accompanying sheets of drawings, which are illustrative of mysaid invention, Figure 1 is a plan view of a sufficient portion of aNobles comb to illustrate the application thereto of my improved dabbingapparatus. Fig. 2 is a similar view to Fig. 1, but is drawn to anenlarged scale, and shows the dabbing apparatus on one side of the comb,that on the other side being identical with it. Fig. 3 is a sectionalelevation of parts shown by Fig. 2 and as seen in the direction of thearrow 00. Fig. 4 is also a sectional view of parts shown by Fig. 2, butas seen in the opposite direction to that indicated by the arrow Fig. 5is an elevation of parts illustrated by Fig. 2 and as seen in thedirection of the arrow g Figs. 6, 7, and 8 represent an elevation, asectional side elevation, and a sectional plan, (on line :r so ofFig.'7,) respectively, of the delivery end of a blast or blow pipehereinafter'described and are drawn to a scale still larger than Figs. 2to 5, inclusive. Fig. 9 is a detail drawing, same scale as Figs. 2 to 5,of one of the plates or blades mounted in the comb-circles, ashereinafter described.

Similar letters and figures of reference indicate similar partsthroughout the several.

views.

In accordance with my said invention I mount, between the rows of pins 1and 2 and those at 3 and 4 in the large comb-circle a, plates or blades0, respectively, which will reach down from the tops of said pins toabout their middle parts, while between the rows of pins 2 and 3 andthose at 4 and on the said circle a. I mount other plates or blades (Zd,

Thus

will occupy alternate positions, while the course or path for the fibersbeneath and above same will be somewhat of a zigzag form, as shown bybroken lines, Fig. 4. I also preferably employ a blade or strip e,similar to those 0 c, and mount it to intervene between the pins 7 and 8of the small comb-circle Z).

By the fibers being constrained to follow a zigzag path, as abovedescribed, they are held from being withdrawn at such parts from thelarge circle a by the lesser circle I), by which means said lesser combb will only separate the shortest and least useful fibers therefrom,while when the large comb a has carried its fibrous substances beyondand clear of the retaining-blades c c and d 01 then the drawing-offrollers are enabled to freely pull same in the usual and well-knownmanner, thus to comb it between the several rows of the said combsteeth.

The blades 0, c, and e are mounted in their bearings f by their bolts orrods 9, g, and 9 so that they are enabled to have slight lateral play orside shake to allow them to accommodate themselves to any irregularitiesthat the rows of teeth in the comb may have from their true circularpaths, while further to allow the fibers or wool to be less firmly heldat certain parts of their or its path under the blades 0 0', so thatalthough still kept well within the interstices between the teeth itrequires less force to be exercised by the small circle, I form thelower edges of the blades 0, c, and e, or any of them, of a serratedshape, as shown in Fig. 9.

To force the fibers or wool down and under the blades 0 c, I conduct acurrent or currents of air or a blast of wind through the pipes h and71; to strike together said fibers or wool at that part of their path ofmotion just before reaching the curved ends of the blades 0 c, and thisblast of wind I make to follow such a path that it will first extend ina thin current across the rows of pins in both of the circles, (or apart of same,) said part of the current passing through the orifice h'ofthe pipe it, while two other parts of the current are conducted tostrike between said rows of pins through the parts 7L2 7L3 of theorifice in the same pipe and that with sufficient force to force thefibers or wool, as desired. The orifice of the pipe 70 is furtherarranged so that it may be adjusted to direct its current of air tocommence the pressure of the fibers to bring them into better positionto be sub sequently acted upon by the succeeding airblast.

Any suitable fan, blower, or air-propelling mechanism may be employedfor producing the currents of air as described.

Such being the nature and object of my said invention, what I claim is Vs 1. In a machine of the character described, including combing pins orteeth, an air-pipe for directing a current of air into the intersticesbetween said pins or teeth and toward their bases;

2; In a machine of the character described, including combing pins orteeth, a flatmouthed air-pipe extending across the rows of pins or teethfor directing a thin current of with the pins or teeth thereof, of anair-blastv pipe for forcing the fibers downward between said pins, andblades for holding the fibers when so forced.

4. In a combing-machine, the combination with the pins or teeth thereof,of an air-blast pipe for forcing the fibers downward between said pinsand blades for holding the fibers when so forced, said blades havingserrated JONAS DENBY.
